ating pawl in different adjustments whereby it will actuate the platenas required to feed the paper varying distances.

It is obvious that the resent invention may be used upon any of tierecording machines containing a revoluble platen which is operable inconnection with the feed rolls to move the paper in line spacing. Forconvenience of illustration I have illustrated my invention combinedwith an adding machine, but I do not restrict myself to use inconnection with adding machines, and I .desire it to be understood thatI claim my invention in any embodiment in which it is capable of use.

.Theplaten 1 is supported upon a shaft 2 which is revolubly journaled inhearings. in a carriage 3. The carriage 3 is laterally movable upon asuitable support L A number of independently acting pressure rolls 5(Fig. 4) are mounted in the carriage and to actuate the paper in itsline spacing movement. Actuation of the paper is effected by directrotation of the platen vthrough the engagement of the actuating deviceswith a ratchet Wheel 5 which is attached to the shaft 2. A rock shaft 6is supported in hearings in the carriage 3 and an arm 7 is attached toone of the ends of said rock shaft. 7has a pin 8 which extends through aslot 9, (Fig. 6), inone of the side members of the carriage 3, andthereby limits the rocking movement of the shaft 6. A spring 10 has itsrear end connected to the pin 8 and its front end connected to a pin 11on the side although an element capable of moving through the slots 13may be moved from one to another of the holes 12 without withdraw- Thearm ing such element from said holes. A small 7 said ratchet wheel andthereby operate the platen and the feed rolls to elfect movement of thepaper in line spacing. A sleeve 16 'is mounted on the outer part of thebolt 14 and holes 12, but incapable of passing through the slots 13.Thus, when the reduced portion 19 bf the sleeve 16 is' seated in any oneof the liol es,12 it will be: retained in such position, 'begause of theinability of said sleeve to ip ss through the slots 13. The:

inner end of the sleeve will beilretainedf in any cbne of the'holes 12inwhic 20- it may be seated bythe power of the springl-j' The outer partof the sleeve 16 is provided with 'a manually engag'eable portion'20, sothat said sleeve may be manuallywithdrawn from any one of the holes 12in which it may be seated, to enable the bolt 14 to be me ved from oneto another of said holes; Thus, the

actuating pawl 15 maybe adjusted in diffGIGHiZ-POSIhlOIIS with respectto the rock shaft 6, so that said actuating pawl will be moved varyingdistances as required to move the paper oneor two or three spaces, asdesired. When the actuating pawl is sup-4 ported at the lowest hole 12it may be operated to move the paper a single space; when supported atthe intermediate hole 12 it may be operated to move the paper twospaces; and when supported atthe, outer hole 12 the actuating pawl maybe operated to move the paper three spaces; and said pawl may beadjusted and retained in either one of' said positions as aboveexplained,

ratchet wheel rule]. said pawl is disengaged 'The freeend of the pawl isactuated toward the ratchet wheel5 by a spring 21 connesting said pawlwith the side'of the carriage. The front end of the pawl 15 is providedwith .alateral extension 22 (Fig; 4),

. which, as the pawl approaches the end of its forward movement, engagesaroller 23 and is thereby disengagedfrom the ratchet wheel. 5. Theroller 23 .is'supported upon a stud extending from the side member ofthe cark riage3, and is in position to disengage the pawl 15 from theratchet wheel 5 atthe same point in the. forward movement of the pawl,

irrespectii e ofi'whetheiflthe pawl is sup ported atone-ortheother ofthe holes 12, g

The shaft 6 may be rocked by any suitable means. In the embodiment showna lever 24 is slidably keyed. on the shaft and is capable' of operationto rock said shaft and thereby movethe-lctuating pawl 15 to a ctu-.

ate the line spacin" devices.

Inthe normalror, idle position ofthe partsf the'projection 22,011 the,pawlv 15 rests against the roller 23, and is thereby retained out of;

engagement with the ratchetwheel, as shown in Fig. 6. Thus, theactuating pawl is normally disengaged from-the ratchet wheel, so thatthe platen may be otherwise rotated independently of said actuating pawland while saidpawl is disengaged therewith' Ihave illustrated myinvention is provided with rock shaft 26 capable of being rocked bymanipulation of the lever 27. Said shaft is provided with an arm 28which is connected with a link 29. The upperfend of the link 29 ispivoted to the rearwardly extendmg arm of the bell-crank lever 30mounted on a support 31. The upper arm of the lever 30 is provided witha slot 32 which receives a roller 33 which is supported by the lever 2%,hen the carriage 3 moves laterally the lever 24: is prevented frommoving laterally by a bracket 24 attached to the support 4: andprojecting on opposite sides of said-lever 24:. When the lever 27 isdrawn forwardly the connections therefrom will actuate-the rod 33 andlower end of the lever 2% forwardly, thereby rocking the shaft 6 andmoving the actuating pawl 15 rearwardly from the position shown in Figs.1 andfi, to the'positions shown in Figs. 2 and 5. Return movement of thelever 27 rocks ,the shaft 6 in the opposite direction, move- ;;ment offsaid shaft 6 being assisted by the spring 10, thereby engaging the pawl15 with theratchet wheel 5 and actuating said therefroni by tlieroller23. The extent of movement of the pawl and of the ratchet wheel 5 willbe determined by the position in which theactuating pawl is supported;that is to shy, whether said pawl is support ed at oneprthe other ofjthe holes 12.

On some occasions it is desirable to permit operation .of the 'shaft 26without moving the paper in lirie spacing. Thisis particularly trne incertain operations of adding machines,- with which I haaeillustratedmyjnve' tion. A lever 34' is pivotally supported at 35 by one of theside members of thecarriagel Thelower end of the lever 34 curves underthe platen shaft, as 'clearly shown' ,in"Fig. 3,',ia1 1dis' providedwith a roundedgcamming part 36 at its end. The

cam. part 36, operates against a stud 37 on tl eside .fof 'tliiecarriage. The cammin'g-like end 36 of the 'l'everj34 coiiperatesf withthe stud 37 to holdthe lever 34 in either of its two adjustments, In oneof said ad'ustmem the part 36 is aboye the agis .0 the stud 37 andthereby holds the lever 34 above the ratchet teeth on the wheel 5 sothat the pawl 15 may engage with said wheel. Movement of the lever 34 tothe position'shown in Fig. 3 carries the cam-like part 36 below the axisof the stud 37, thereby holding the arcuate under edge of the lever 34below the teeth of the Wheel 5, so that the projection 22 on thepaWl-15rubs against the under edge of said lever 34 and is thereby preventedfrom engaging the ratchet wheel. Thus, the pawl 15 may be moved withoutactuating the platen, as a result of which adjustinent the shaft 26 isenabled to operate without feeding the paper. An extension 39 on theupper end of the lever 34 constitutes a handle for manual engagement foroperating said lever. It ;will be understood that the lever yields topermit movement as.

required to engage the portion 36 above or below the stud 37 as aboveexplained.

Movement of-the lever 34 is limited by a pin 40 on the side of thecarriage extending into a slot 41 in the lever.

The platen detent includes an anal or lever 42 pivoted .upon a support43 and having a small roller 44 operating upon the perip'hery of thewheel 5 so as to hold the platen in its different line space adjust-,ments. A pin 45 on the arm 42 extends through a slot in the side of thecarriage 3.

A spring 46 connectsthe pin 45 with a projection on the carriage andthereby yieldingly holds the roller 44 upon the ratchet Wheel, butpermitsrotation of the ratchet wheelwhen the pawl 15. is actuated. 'Ihave illustrated my invention mounte in a Dalton adding machine, withprovision for operating the lever 24 from one of the shafts of theadding machine. It is to be understood, however, that I do not restrictmyself to an embodiment in which the lever 24 is mechanically operated,for it'is obvious that 1 said lever may be manually operated, which maybe the preferred method of operation when the invention is used upon atypewriter. It is apparent also that there may be .pther variations inthe construction and fariangement of the parts to conform to therequirements of different machines, and that isuch variations are withvin the mechanical skill of those skilled in 'saidratchet Lwl eel, means7 6 5 I 1 the art and are clearly embraced within the scope of thepresent invention.
